Ya know what this game needs? Replays!
As it is right now, everybody is showing off their trap setups with screenshots and videos, which is fine, but I think we could do a step better.
What if there was a way, after playing a level, to save a replay of the level so you could either go back and watch it later, or share it with your friends? You'd be able to either watch the game through their eyes, or freely fly around the stage watching from whatever angle you choose.
I don't know how easily this could be implemented into OMD2 though... maybe that's something best left for OMD3 (if there IS going to be one!)
